PIPELINE & PROCESS

Midstream & Downstream

ADA’s compressed air and membrane nitrogen packages have a wide range of applications for pipelines and process systems during construction, testing, pre-commissioning, commissioning, operations, maintenance, transportation, storage, shutdown/turnaround and decommissioning activities.

Nitrogen is a colourless, odourless, naturally occurring gas. Its inert, non-flammable, non-corrosive, non-toxic properties make it idealfor a number of functions related to displacing an undesired atmosphere (whether air or hydrocarbon) as well as keeping air away from products. The main requirements are the avoidance of any risk of explo- sion, a safe startup and shutdown, the prevention of safety and health hazards during maintenance and the protection against atmospheric oxygen or moisture to avoid corrosion and deterioration of the final product. Nitrogen is also well-suited for drying pipelines and process systems, due to its very low dew point and its ability to readily absorb moisture.

Compressed Air Packages

ADA is able to offer customers total project solutions from its early involvement during the engineering phase through to provision of complete equipment packages including skilled project supervisors, technicians and operators with all the appropriate procedures and health, safety, environmental management and quality systems in place.

ADA complies with most environmental protection regulations and can provide “rig safe” equipment when required.

We bring experience and know-how in building and operating air packages for projects in the most remote and environmentally challenging areas of the world the freezing Canadian winters, the scorching deserts of northern Iraq or the humid jungle high- lands of Papua New Guinea.

Booster Compressors

ADA owns and operates a large fleet of high pressure, silenced rotary screw air compressors with a range of specifications to produce up to 1500 scfm at 350-500 psi. All units can be transported inside or as ISO containers; some are DNV certified for offshore use.

Membrane Nitrogen Generators

ADA’s Membrane Nitrogen Generators can deliver a guaranteed, uninterrupted, on-demand supply of nitrogen gas for a wide range of uses, generated on site at controlled, variable flows, pressures and purity levels.

Our containerised membrane generators are highly mobile, low-maintenance, reliable, environmentally friendly, simple and safe to operate. They are designed to perform in any environmental condition and are especially beneficial over cryogenic systems for remote and logistically challenging locations where the delivery of liquid nitrogen is often too difficult and costly. The losses and hazards associated with the storage, transport and handling of cryogenic liquids do not apply to membrane nitrogen systems.

Upstream

ADA can generate nitrogen on site for a number of upstream applications. Its inert, low density and high pressure characteristics make nitrogen an ideal choice for drilling, workover and CTU operations. Being immiscible with oil and water, nitrogen can also be used to enhance well/reservoir production.

Air Dryers & Oil Removal Filters

Desiccant air dryers can be deployed to bring the pressure dew point of the compressed air down to between -40F to -80F as required.

Coalescing oil removal filters are used when the compressed air must have minimal oil content, or in some cases be virtually “free”.

Rotating Control Devices (RCDs)

The Elite Drill Master “DM-Series” RCD’s are one of the industries newest passive rotating control devices. The DM-Series heads are designed and tested in accordance with specification API 16-RCD. These RCD’s incorporate several unique patent pending designed components intended to make this product one of the safest and most operationally efficient available.

Air Drilling Associates has about 10 RCD’s in its fleet, including the following types:
